DEVICE AND METHOD FOR THE LIQUID-TIGHT SEALING OF TWO PARTIALLY OVERLAPPING PACKAGING PARTS AND CONTAINERS PRODUCED THEREWITH/THEREBY

摘要

A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.
